Letters Patent No. 103,929, dated Jzmc 7, 1870.

IMPROVEMENT IN GAS-RETORTS.

The Schedule referred to in these Letters Patent and making part of the saule .oqw

To all whom it may concern Be it known that we, Jarras RleBYanl-l PHILIP A. PALMER, of Marietta, in the county of `Washing` ton and State of Ohio, have invented a new and useful Improvement in Gas-Retorts; and we do hereby declare that the following is a full and exact description of the same, reference being had to the accompanyiu g drawing and to the letters of reference marked thereon.

This invention relates to that cla-ss of gas-retorts which is especially designed for use ill counectioll with oils, rosin, paraiiine, 83o.

It also consists in certain details of construction, which will be fully described hereinafter.

In the drawing* Figure l represents a side sectional elevation Figure 2, a transverse sectional elevation;

Figure 3, an end elevation; and

Figure 4a side elevation.

To enable others skilled in the art to which our invention appertains to make and use the saule, we will now proceed to describe fully its construction and operation.

A represents the retort, which -is constructed with the sides d a alld top and bottom al a2. It will be observed that the bottom (t2 ismuch narrower than the top a, by which means a triangular or V-shaped form is given to its cross-section.

v B represents a corrugated pla-te, which extends longitudinally nearly the entire length' of the retort, and

' .is loomed anale below tno longitudinal conter uno,

as shown in iig. 1. rlhis plate is also inclined in a downward direction from the front to the rear of the retort.

d represents the receiver, by means of which the oil or other material Afroln which this gas is to be manufactured is introduced into the retort. o

d represents the pipe by means of which the manufactured gas is conveyed to the holder. y

E represents a removable plate which covers the rear endof the retort, and is secured thereto ill any suitable lnanner, the end being made open, for the purpose of making the entrance of the retort easily accessible, when desired, for inspection and cleaning boxes. If desired, the end may be cast solid, with the exception of two small holes, one at the bottom of the retort and the other on a level with the outlet at the back of the retort. These are closed by means of screw-plugs.

The operation is as follows:

The oil or other material from which the gas is to lbe manufactured is poured int-o the recciver,'and is4 tllus introduced illto the retort. The gas is -lnanufactured in chamber c, and collects in Achamber b, and is delivered through the pipe d. If the oil should chance to arise in vapor, it falls on a corrugated plate, and is there generated in gas, thus preventing the accumulation of crude oil. The peculiar shape of the retort causes tile-oil or other material to lie in acompalct mass, and the heat, consequently, is readily applied thereto in a concentrated nlanner. A great saving of fuel is necessarily e'ected, alld an increased production of gas, also, is obtained from the process.

IVe do not linlit ourselves to the employment of any special material in our retort, but-shall employ any substances that are adapted for our purpose.

Having thus fully described our invention,

IVhat we claim as new, and desire to secure hy Letters Patent, is

Tile retort described, having the walls a, a al a?, plate B, receiver d, pipe d', when colnbilled as dcscribed, for the purpose set forth.

Ihis specification signed and witnessed this 14th day of A'plil, 1870.
